slow desktop - slackware & fluxbox


Ive got a problem with my Slackware 12.1 & Fluxbox desktop.

its strangely slow, only by a split second, but its noticeable. when I open Gftp or Xpdf or some other program, the window gets drawn as a block of grey, then it will fill in the fonts. I dont think its a Slack/Fluxbox problem, because Ive used the same versions for a while with good results on another computer (P4).

I should tell you, my current computer is an Intel Celeron 2.6, with 768m of RAM.

I tried moving/reseating the RAM to no effect, and Ive run 'memtest86' and everything seems ok no errors. Ive also tried Slackwares default kernel 'hugesmp.s', and the 'huge.s' kernel.

is there a program that I can test the Celeron processor with? do Celerons need special kernel options?

any other suggestions on what I can try next?

The problem may be with the configuration of the graphics driver; if you use a generic driver like "vesa" or "vga", you will not have any 2D acceleration.

A kernel compiled for "i686" should have support for the Celeron's features. If your system uses an 'i686' kernel and libc, then you will be making good use of the CPU's features. If the system is a generic i386 or i486 (and the same for libc) then you can get some improvements by changing libc and the kernel.

If fonts slow things down, check the antialias settings; if font antialiasing is being done by software that can really slow things down. Once again, if the GPU supports the operations and you use the correct driver then you will see a big improvement.

thankyou, the problem was indeed the video driver.

Im embarrassed to say, I hadnt run 'xorgconfig' and selected the correct driver for my onboard video lol.

I thought the default VESA driver would work fine, so thought it must have been something else.

anyway, it works very nicely now, windows are drawn fully and immediately.

thanks again pinniped
